No communication!!! Might have lost my device to bad service!

I sent my watch to Garmin to be assessed. They never confirmed receipt and when I asked they took a 5 days to get back to me saying they have received it and will let me know once it has been assessed. 3 weeks and no correspondence! I fear that I might not get my device back. Extremely poor service and will not recommend buying a Garmin - their service horrible!
